All I have to say is be very, very, careful about environmental movements. There are legitimate problems with the environment. But the solutions people offer to these problems often involve police-state measures. If the government wants someones property allegedly because of some owl, let them negotiate the price with the owner. Don't just put restrictions on the land making it worthless. I am not against setting aside land for forest preserves. They are nice places to visit. But again, buy it, don't steal it. There is a forest preserve within walking distance from my house. The farmer who owned the land sold it way below market value just to keep it wild. Sometimes people are willing to make sacrifices.
I got involved with a local environmental organization that advocated land grabs, or "wildlife corridors" as they called it. The idea is that global warming makes it necessary to grab vast amounts of land for wild animals to cross as the climate changes. First of all, most of the wilderness in this country is in mountainous areas, with little or no human use except for mining and logging operations. Mines do cause problems, but loggers do not clear cut forests like they used to. For every tree they cut down, they plant a new tree. First of all, because it is the law, and second of all, because they do not want to destroy the future of their business. So the vast areas of wilderness out west are in no danger of dissapearing. And they are vast. I have often driven though Colorado, Whyoming, and Montana, and let me tell you, if your car breaks down, you are in trouble. It is nothing but wilderness. This wilderness extends, with few exceptions, all the way to the coastal states. There are ranchers in the less isolated areas, but they also have an interest in not spoiling the land. All I will say is the organic food market is growing, and the bigger it gets, the more organic farmers you will see. I really would suggest Americans to take a road trip through these areas before the price of gas makes it impossible.
So as the climate gets warmer, the animals will either move north, or climb up the mountains, which ever is easier. As for reducing carbon emissions, right now, people have no options. The oil companies conspired to rip up thousands of miles of rail in this country, which they did. And it has been proven that auto makers have been suppressing more efficient engine technology.
I used post on a forum called peakoil.com. They took a legitimate concern, that gas and oil supplies are about to peak, and make a doomsday religion out of it. It has become a haven for malthusian population reductionists. This blog
http://peakoildebunked.blogspot.com/ is made up of folks who have become disillusioned with the peak oil crowd. I believe there is a problem, but what the powers that be have in mind is to sit on the remaining oil fields, artificially raising the price of oil. If they have their way, no attempt will be made at finding a replacement for oil. There is plenty of evidence of that. There are solutions, but nobody is persuing them. One rule of thumb is that if the government endorses a "solution" such as the "hydrogen econony", than it is not a solution. Hydrogen is an energy has to be manufactured, usually by extracting it from natural gas. A more practical solution would be to rebuild our rail network, adopt suppressed fuel-efficient engine designs with bio-diesel as fuel. I don't know if abiotic oil theories are valid or not. It is a problem that the world's best experts on oil work for oil companies.
The more I think about these issues the worse it seems. I have to stop myself now so I can get some sleep.
